I have one pipeline and one other job. i want to pass parameter.
This is my groovy script which is inside pipeline job.
pipeline {
agent any
stages {
stage('release') {
steps {
echo 'This is release!'
echo branch
build job: projectname , parameters: [[$class: 'StringParameterValue', name: 'branch', value: branch]]
}
}
So this branch i want to pass into build job. echo branch also printing perfectly.
And this is how i tried to get my branch name from release job
This trigger an error.
org.tmatesoft.svn.core.SVNException: svn: E160005: Target path '/${branch}' does not exist
It does not resolve to the branch name which i want
This should work:
build job: projectname , parameters: [string(name: 'branch', value: "${branch}")]

I have a below pipeline job.
http://abc:8080/job/US/job/UK/job/UAT/job/DEVOPS/job/Testing/job/test-readcsv/configure
Within the groovy script of above job I need to trigger the below job.
http://abc:8080/job/US/job/UK/job/UAT/job/DEVOPS/job/Release/job/1.5.5.11-Release/configure
Can someone please help in triggering the job.
I am using below command but it gets failed with error - java.lang.NoSuchMethodError: No such DSL method '$' found among step
echo "Triggering job for branch ${env.BRANCH_NAME}"
build job: "../../Release/1.5.5.11-Release", wait: false , parameters: [string(${csvContent}) , string(${params.param1}), string(${params.param2})]
Here is an example of how I do it in one of my Jenkins files. That error you're seeing is possibly because your parameters are not in double quotes.
stage('Trigger Pipeline'){
steps {
script {
build job:'Path/to/job' , parameters:[
string(name: "param1", value: "${params.foo}"),
string(name: "param2", value: "${params.bar}"),
]
}
}
}
I am new to Jenkins pipeline.
I have a jobA and jobB inside jobA how to send the latest ${BUILD_NUMBER} of jobA to jobB
stage('Run')
{
steps
{
dir ('/path')
{
build job: 'abc'; <How to send the ${BUILD_NUMBER} here>
build job: 'cde';
build job: 'rrr';
}
}
You can achieve it as follows:
build job: 'abc',
parameters: [
string(name: 'build_number', value: String.valueOf(BUILD_NUMBER))
]
I have two Jenkins pipelines, let's say pipeline-A and pipeline-B. I want to invoke pipeline-A in pipeline-B. How can I do this?
(pipeline-A is a subset of pipeline-B. Pipeline-A is responsible for doing some routine stuff which can be reused in pipeline-B)
I have installed Jenkins 2.41 on my machine.
Following solution works for me:
pipeline {
agent
{
node {
label 'master'
customWorkspace "${env.JobPath}"
}
}
stages
{
stage('Start') {
steps {
sh 'ls'
}
}
stage ('Invoke_pipeline') {
steps {
build job: 'pipeline1', parameters: [
string(name: 'param1', value: "value1")
]
}
}
stage('End') {
steps {
sh 'ls'
}
}
}
}
Adding link of the official documentation of "Pipeline: Build Step" here:
https://jenkins.io/doc/pipeline/steps/pipeline-build-step/
A little unclear if you want to invoke another pipeline script or job, so I answer both:
Pipeline script
The "load" step will execute the other pipeline script. If you have both scripts in the same directory, you can load it like this:
def pipelineA = load "pipeline_A.groovy"
pipelineA.someMethod()
Other script (pipeline_a.groovy):
def someMethod() {
//do something
}
return this
Pipeline job
If you are talking about executing another pipeline job,
the "build job" step can accomplish this:
build job: '<Project name>', propagate: true, wait: true
propagate: Propagate errors
wait: Wait for completion
If you have paramters on the job, you can add them like this:
build job: '<Project name>', parameters: [[$class: 'StringParameterValue', name: 'param1', value: 'test_param']]
As mentioned by #Matias Snellingen and #Céline Aussourd, in the case of launching a multibranch job you have to specify the branch to build like this :
stage ('Invoke_pipeline') {
steps {
build job: 'pipeline1/master', parameters: [
string(name: 'param1', value: "value1")
]
}
}
In my case it solved the problem.
I am going to post my solution, which is similar to #Michael COLL, #Matias Snellingen, and #Céline Aussourd.
For the multibranch pipeline I am using the following code in Jenkinsfile to trigger my multibranch B with multibranch A (in the example there are two cases for pipeline and multibranch pipeline):
post {
always {
echo 'We are in post part and Jenkins build with QA tests is going to be triggered.'
// For triggering Pipeline
//build job: 'WGF-QA WITH ALLURE', parameters: [string(name: 'QA-Automation', value: 'value from Build pipeline')]
// For triggering Multibranch Pipeline
build job: 'Testing QA/QA Selenium Tests/feature%2FGET-585', parameters: [string(name: 'QA-Automation', value: 'value from Build pipeline')]
}
}
Just be sure to define the whole path to the branch as is defined in the case and instead of / in branch name use %2F (feature/GET-585 -> feature%2FGET-585).
To add to what #matias-snellingen said. If you have multiple functions, the return this should be under the function that will be called in the main pipeline script. For example in :
def someMethod() {
helperMethod1()
helperMethod2()
}
return this
def helperMethod1(){
//do stuff
}
def helperMethod2(){
//do stuff
}
The someMethod() is the one that will be called in the main pipeline script
Another option is to create a package, load it and execute it from the package.
package name.of.package
import groovy.json.*
def myFunc(var1) {
return result
}
Than consume it
#Library('name_of_repo')
import name.of.package.*
utils = new name_of_pipeline()
// here you can invoke
utils.myFunc(var)
hope it helps
We have a build and deploy process for every artifact. If build or deploy for a single artifact fails it should not stop the whole process.
We have a separate jobs for build and deploy. Build jobs can work in parallel on a slaves, deploy not.
The results of a build job should be used by deploy job. I need somehow to get a workspace location of a build and set it as a parameter of a deploy job. The place where I need to put a workspace is marked with a question mark.
def branches = [:]
def artifactsToDeploy = []
node{
workspace = pwd()
echo "Workspace:${workspace}"
//read artifact names from file
def appFile=readFile(workspace+"#script/artifacts.txt")
def artifactNames = appFile.tokenize()
//prepare parallel jobs
for (int i=0 ; i < artifactNames.size ; i++) {
def artifactName=artifactNames[i]
branches[artifactName]={
//start build job
def buildResult = build job: 'build-artifact', parameters: [[$class: 'StringParameterValue', name: 'ARTIFACT', value:artifactName],
[$class: 'StringParameterValue', name: 'SVN_TAG', value:SVN_TAG]]
//need to read workspace from a build job, that was running on a slave
artifactsToDeploy[artifactsToDeploy.size]=[artifact:artifactName,workspace:?????]
}
}
echo 'pipeline begin'
stage('build'){
parallel branches
}
stage('deploy'){
//read artifacts from a list and deploy
for (int i=0;i<artifactsToDeploy.size;i++) {
def buildResult = build job: 'deploy-artifact', parameters: [[$class: 'StringParameterValue', name: 'ARTIFACT', value:artifactsToDeploy[i].artifact],
[$class: 'StringParameterValue', name: 'WORKSPACE', value:artifactsToDeploy[i].workspace]]
}
}
echo 'pipeline end'
}
You shouldn't need to have the workspace available in the downstream build, just use archive to make the artifact persistent and pass the reference in a parameter to the job which needs to know about it, then use Copy Artifact Plugin to get the artifact in the downstream job.
There is a rawBuild, that can be used. To access a workspace use buildResult.rawBuild.environment.WORKSPACE
How can I trigger build of another job from inside the Jenkinsfile?
I assume that this job is another repository under the same github organization, one that already has its own Jenkins file.
I also want to do this only if the branch name is master, as it doesn't make sense to trigger downstream builds of any local branches.
Update:
stage 'test-downstream'
node {
def job = build job: 'some-downtream-job-name'
}
Still, when executed I get an error
No parameterized job named some-downtream-job-name found
I am sure that this job exists in jenkins and is under the same organization folder as the current one. It is another job that has its own Jenkinsfile.
Please note that this question is specific to the GitHub Organization Plugin which auto-creates and maintains jobs for each repository and branch from your GitHub Organization.
In addition to the above mentioned answers: I wanted to start a job with a simple parameter passed to a second pipeline and found the answer on http://web.archive.org/web/20160209062101/https://dzone.com/refcardz/continuous-delivery-with-jenkins-workflow
So i used:
stage ('Starting ART job') {
build job: 'RunArtInTest', parameters: [[$class: 'StringParameterValue', name: 'systemname', value: systemname]]
}
First of all, it is a waste of an executor slot to wrap the build step in node. Your upstream executor will just be sitting idle for no reason.
Second, from a multibranch project, you can use the environment variable BRANCH_NAME to make logic conditional on the current branch.
Third, the job parameter takes an absolute or relative job name. If you give a name without any path qualification, that would refer to another job in the same folder, which in the case of a multibranch project would mean another branch of the same repository.
Thus what you meant to write is probably
if (env.BRANCH_NAME == 'master') {
build '../other-repo/master'
}
You can use the build job step from Jenkins Pipeline (Minimum Jenkins requirement: 2.130).
Here's the full API for the build step: https://jenkins.io/doc/pipeline/steps/pipeline-build-step/
How to use build:
job: Name of a downstream job to build. May be another Pipeline job, but more commonly a freestyle or other project.
Use a simple name if the job is in the same folder as this upstream Pipeline job;
You can instead use relative paths like ../sister-folder/downstream
Or you can use absolute paths like /top-level-folder/nested-folder/downstream
Trigger another job using a branch as a param
At my company many of our branches include "/". You must replace any instances of "/" with "%2F" (as it appears in the URL of the job).
In this example we're using relative paths
stage('Trigger Branch Build') {
steps {
script {
echo "Triggering job for branch ${env.BRANCH_NAME}"
BRANCH_TO_TAG=env.BRANCH_NAME.replace("/","%2F")
build job: "../my-relative-job/${BRANCH_TO_TAG}", wait: false
}
}
}
Trigger another job using build number as a param
build job: 'your-job-name',
parameters: [
string(name: 'passed_build_number_param', value: String.valueOf(BUILD_NUMBER)),
string(name: 'complex_param', value: 'prefix-' + String.valueOf(BUILD_NUMBER))
]
Trigger many jobs in parallel
Source: https://jenkins.io/blog/2017/01/19/converting-conditional-to-pipeline/
More info on Parallel here: https://jenkins.io/doc/book/pipeline/syntax/#parallel
stage ('Trigger Builds In Parallel') {
steps {
// Freestyle build trigger calls a list of jobs
// Pipeline build() step only calls one job
// To run all three jobs in parallel, we use "parallel" step
// https://jenkins.io/doc/pipeline/examples/#jobs-in-parallel
parallel (
linux: {
build job: 'full-build-linux', parameters: [string(name: 'GIT_BRANCH_NAME', value: env.BRANCH_NAME)]
},
mac: {
build job: 'full-build-mac', parameters: [string(name: 'GIT_BRANCH_NAME', value: env.BRANCH_NAME)]
},
windows: {
build job: 'full-build-windows', parameters: [string(name: 'GIT_BRANCH_NAME', value: env.BRANCH_NAME)]
},
failFast: false)
}
}
Or alternatively:
stage('Build A and B') {
failFast true
parallel {
stage('Build A') {
steps {
build job: "/project/A/${env.BRANCH}", wait: true
}
}
stage('Build B') {
steps {
build job: "/project/B/${env.BRANCH}", wait: true
}
}
}
}
The command build in pipeline is there to trigger other jobs in jenkins.
Example on github
The job must exist in Jenkins and can be parametrized.
As for the branch, I guess you can read it from git
Use build job plugin for that task in order to trigger other jobs from jenkins file.
You can add variety of logic to your execution such as parallel ,node and agents options and steps for triggering external jobs. I gave some easy-to-read cookbook example for that.
1.example for triggering external job from jenkins file with conditional example:
if (env.BRANCH_NAME == 'master') {
build job:'exactJobName' , parameters:[
string(name: 'keyNameOfParam1',value: 'valueOfParam1')
booleanParam(name: 'keyNameOfParam2',value:'valueOfParam2')
]
}
2.example triggering multiple jobs from jenkins file with conditionals example:
def jobs =[
'job1Title'{
if (env.BRANCH_NAME == 'master') {
build job:'exactJobName' , parameters:[
string(name: 'keyNameOfParam1',value: 'valueNameOfParam1')
booleanParam(name: 'keyNameOfParam2',value:'valueNameOfParam2')
]
}
},
'job2Title'{
if (env.GIT_COMMIT == 'someCommitHashToPerformAdditionalTest') {
build job:'exactJobName' , parameters:[
string(name: 'keyNameOfParam3',value: 'valueOfParam3')
booleanParam(name: 'keyNameOfParam4',value:'valueNameOfParam4')
booleanParam(name: 'keyNameOfParam5',value:'valueNameOfParam5')
]
}
}
